hwmon: tmp108: fix I3C dependency

It's possible to build a kernel with tmp108 built-in but i3c support
in a loadable module, but that results in a link failure:

x86_64-linux-ld: drivers/hwmon/tmp108.o: in function `p3t1085_i3c_probe':
tmp108.c:(.text+0x5f9): undefined reference to `i3cdev_to_dev'

Add a Kconfig dependency to ensure only the working configurations
are allowed.
